SBP, systolic blood pressure; DBP, diastolic blood pressure; BCVA, best-corrected visual acuity; CRT, central retinal thickness. At month 12, CRT, intraocular pressure, and acircularity index were abnormally distributed ( values: <0.0001, 0.0423, 0.0002, respectively, in Shapiro–Wilk’s test). The Spearman correlation was used to examine correlations with other variables. Pearson correlations were analyzed for others. .
